What has changed since you last performed it and it was well received? Have you lost interest in the piece? Do you think audiences have shorter attention spans now than they did then? Personally, I love the piece, and I think the second movement is one of the most beautiful things ever written. The whole sonata is full of love of life and nature, the fear of impending death, tenderness, wistfulness, resignation. But if you are worried that it will be boring, then maybe better just to pick something else.
It's a different time (the last performance was 10:30am, and the Sonata was the whole recital). This time, it will be late (starting at about 8:45pm), and it's the second half of a program (the first half will be a dozen Schubert lieder- then the people will have had a light meal- including drinks- during interval).So, yes, I feel that this particular audience will have a shorter attention span....
In that case, depending on whether you already have them performance ready, you might think of dropping that sonata and replacing it with some of his Impromptus. They are also beautiful, and they are less demanding to listen to, I think. I do think you are right, and audience with full stomachs, a non-zero blood alcohol, and a late hour may not be right for such a long, serious piece.
…then the people will have had a light meal- including drinks- during interval).So, yes, I feel that this particular audience will have a shorter attention span....
How did the performance go?
I played the whole Sonata (as advertised) making just a small abridgement to the second movement (skipping about 16 bars on the last page), which seemed to be getting boring..
